      The cartridge arrived the next day as promised but sadly proved faulty. However, after a phone call to a very helpful employee, a replacement cartridge was despatched, arriving within 24 hours as promised. Speedy delivery, easy installation, good print quality, sensible price with no postal charges all make Cartridge Save an excellent company. The printer in question is an elderly HP Deskjet 810C - and Cartridge Save compatible High Capacity Black cartridges are ideal and extremely good value.

      By Dave May on

      Very poor quality : contacts were dirty, slight leakage, and does not seem to work properly ( colours fade soon after printing has started, and then merge into a pale grey, eventually stopping the ink flow altogether. )......
      I would say that unlike the Tri-Colour above, previously purchased Black single colour cartridges do seem to be ok.

      By Peter Davidson on

      Very good rapid service, but the ink colours had been tainted by leakage and were unacceptable. However the problem was quickly resolved by a refund and I have always found the customer service to be excellent, and this is the first time I have ever had a problem with quality of a cartridge from this company.

        3-year warranty on our own-brand cartridges
        We are proud of our own-brand cartridges, so we’ve made trying them a no-brainer. If within three years of purchase you have any problem whatsoever, we’ll happily offer either a replacement or a refund.
        Returning items is easy—it takes just a few minutes. But our return rate is very low, so you’ll be unlikely to need it.
        We are confident that no other own-brand cartridges are better than ours. They produce vibrant prints with accurate colour densities and dark blacks—and their page yields are as good as the genuines, if not better. Give them a try, and see why our customers love them.
        Our own-brand cartridges are incredibly reliable for three reasons:
        1. We are the UK’s biggest seller of own-brand cartridges, and we have invested a lot in optimising them.
        2. We are dedicated to quality. Every own-brand cartridge is performance-tested before it leaves the factory.
        3. We constantly monitor customer feedback, and quickly resolve any issues.

HP Deskjet 3820 Printer Review

Expert review of the HP Deskjet 3820 printer

Our Verdict:

This bargain device is part of HP's redesigned series of inkjet printers that promises speed and efficiency for home and personal use. Excellent photo output and the low initial cost are among the best things about the HP Deskjet 3820, but users may not be happy with the quality on text and graphics as well as its overall speed and running costs.

Design

The 'tissue box' look and lightweight plastic casing of the HP Deskjet 3820 makes it quite light at 11.7 pounds and compact at 7.6 inches tall, 20.0 inches wide, and 14.8 inches deeps. This inkjet printer can be linked to your PC or Mac using either a Parallel or USB connection. The HP Deskjet 3820 is integrated with HP ColorSmart III / HP PhotoREt III image enhancement technology for printing high-resolution photos.

Advantages

Amateur photographers may find the HP Deskjet 3820 a good choice because of its high-quality photo prints. Text printing is adequately fast at 12 ppm in draft, 6 ppm for 'normal' monochrome, and 10 ppm for mixed colour and text draft.

Disadvantages

The 2 MB RAM is often insufficient and renders this device slow. The HP Deskjet 3820 does not have high-yield ink cartridges, so expect running costs to be high. The flimsily-designed hardware and casing makes this device too fragile for heavy use. The USB cable is not included in the package when you buy the HP Deskjet 3820. Text and graphics look mediocre, too.
